The genus Citrus contains a vast range of antioxidant metabolites, dietary metabolites, and antioxidant polyphenols that protect plants from unfavorable environmental conditions, enhance their tolerance to abiotic and biotic stresses, and possess multiple health-promoting effects in humans. This review summarizes various antioxidant metabolites such as organic acids, amino acids, alkaloids, fatty acids, carotenoids, ascorbic acid, tocopherols, terpenoids, hydroxycinnamic acids, flavonoids, and anthocyanins that are distributed in different citrus species. Among these antioxidant metabolites, flavonoids are abundantly present in primitive, wild, and cultivated citrus species and possess the highest antioxidant activity. We demonstrate that the primitive and wild citrus species (e.g., Atalantia buxifolia and C. latipes) have a high level of antioxidant metabolites and are tolerant to various abiotic and biotic stresses compared with cultivated citrus species (e.g., C. sinensis and C. reticulata). Additionally, we highlight the potential usage of citrus wastes (rag, seeds, fruit peels, etc.) and the health-promoting properties of citrus metabolites. Furthermore, we summarize the genes that are involved in the biosynthesis of antioxidant metabolites in different citrus species. We speculate that the genome-engineering technologies should be used to confirm the functions of candidate genes that are responsible for the accumulation of antioxidant metabolites, which will serve as an alternative tool to breed citrus cultivars with increased antioxidant metabolites.

Excessive Accumulation

Abiotic and biotic stresses induce the formation of reactive oxygen species (ROS), which subsequently causes the excessive accumulation of aldehydes in cells. Stress-derived aldehydes are commonly designated as reactive electrophile species (RES) as a result of the presence of an electrophilic α, β-unsaturated carbonyl group. Aldehyde dehydrogenases (ALDHs) are NAD(P)+-dependent enzymes that metabolize a wide range of endogenous and exogenous aliphatic and aromatic aldehyde molecules by oxidizing them to their corresponding carboxylic acids. The ALDH enzymes are found in nearly all organisms, and plants contain fourteen ALDH protein families. In this review, we performed a critical analysis of the research reports over the last decade on plant ALDHs. Newly discovered roles for these enzymes in metabolism, signaling and development have been highlighted and discussed. We concluded with suggestions for future investigations to exploit the potential of these enzymes in biotechnology and to improve our current knowledge about these enzymes in gene signaling and plant development.

Representative Samples

How does engagement in multiple health behaviors consolidate into health promoting health lifestyles, and how does economic development provide a broadly shared living condition to enable participation in health promoting health lifestyles? To answer these questions, we harmonize information from the 2011 International Social Survey Programme and the 2014 European Social Survey to examine patterns of health lifestyles and subsequent associations with self-rated health in representative samples of 52 country-years nested in 35 countries, with repeated observations from 17 countries. We find individuals engage more frequently in health promoting behaviors in countries with higher levels of economic development. Moreover, we find a tighter connection between health lifestyles and health in countries with higher levels of economic development. Critically, we move health lifestyles research forward by testing the consequences of within country changes in economic development, finding that growth in economic development increases the engagement of health promoting health behaviors. Policy and theoretical implications are discussed.

Mouse ornithine decarboxylase (ODCase) cDNA was expressed at a high level in an Escherichia coli mutant deficient in polyamine biosynthesis. The expression of mouse ornithine decarboxylase relieved the dependence of the mutant on an exogenous source of polyamines, presumably by providing putrescine, the product of the enzyme. The effect on the enzymatic activity of deletions that removed carboxy-terminal amino acids of the protein was determined.
